PMP9202: Transformer Specification needed

Hi Jil,

Thank you for your inquiry, I'll check with an engineer, is there any manifacturing specifiaction exist in TI internally. However, so far the quickest way is asking Renco directly on RLTI-1067. https://www.rencousa.com/products/rlti-1067 

Please take a contact to see whether they provide you the information that you need .engineering@rencousa.com

If you have any question, please let me know.

Regards,

Yuki

Hi,

The link to the Renco transformer drawing is in the previous post by Yuki.  Here are the original electrical specifications for this transformer.

Hi Jil,

The transformer for this supply was designed by Renco (contact information provided in the previous post), based on the electrical requirements.  I do not know the exact number of turns used in the design, however the winding ratios are 13.5:1:4(Pri:Sec:Bias).

thank you,

Brian
